RC 5535 1.5 Crown electric forklift specs & dimensions (2009 - 2021)

Crown Drive System

Crown has applied the latest generation AC drive system, enhanced with Access 1 2 3 technology. The demand for high efficiency systems that closely match customer torque requirements is met with the generation control system. Crown-manufactured, independently controlled, AC drive motors are specifically designed to optimise system integration between the traction and braking controls. Crown’s Access 1 2 3 technology provides optimum performance and control by offering a communication interface for operators and technicians, intelligent coordination of lift truck system and simplified service with advanced diagnostics. The Crown display is used for easy troubleshooting, access service history and set performance features. A distribution panel is conveniently located with all test points, control fuses and central wiring for easy troubleshooting. Three modes of performance can be selected to accommodate operator experience or application requirements.

e-GEN™ Braking System

Variable regenerative motor braking is optimised and virtually eliminates brake maintenance. The appropriate amount of stopping force is applied to match operator brake input and the current operating conditions of the truck.

Steering

Load-sense hydrostatic steering is an on-demand system which reduces energy consumption. Smooth, quiet steering control with minimal operator effort required at the steer tiller. Steer tyres rotate 182° for maximum manoeuvrability. Crown’s hydrostatic steering system is simplified with significantly fewer parts, thus reducing maintenance requirements.

Mast Assembly

Crown-manufactured mast assembly utilises a “flush-face” interlocked I-beam design to improve visibility and reduce truck length. Roller bearing studs are welded on both sides of the rails for maximum strength, and roller bearings are canted to run in the thick cross section of the rail. Tie bars wrap around the rails for added strength and to resist off-centre load forces. “In-line” hose routing opens up visibility, while cylinders are placed to the sides to create a high visibility design. The mast has four points of attachment to the truck for good load force distribution, with two mounting points at the frame where tilt cylinders attach. Tilt cylinders use spherical bushings to resist off centre load distortions, and two large diameter studs secure the mast to the drive units.

Drive Units

Two Crown-manufactured independent double reduction planetary gear drives offer 27 to 1 gear reduction. The first and second reduction use helical gears for low noise and efficiency. The drive unit gears are splash lubricated in an oil bath.
